Re: Found Original Psion USA Cartridges

Practice on some crap ones first! The main issue is the old sponge not coming off properly. Sometimes it falls off in one piece, other times you end up with a thin layer of gunk and Verdigris on the brass spring plate and you have to scratch and rub away for ages... which if you're unlikely will cau...

Re: Found Original Psion USA Cartridges

I'm going to re-felt them and then see how healthy they are, what I can get to run etc. Be interesting to see if there are references to the UK names, what the red start screen looks like etc.

Found Original Psion USA Cartridges

CST RAM-Plus, large pics thereof

I've had this for a 6+ months and it didn't work. It looked like a previous owner had messed with it and there was some messy soldering and something or other missing from the PCB. It was so messy, I couldn't even see that the missing component had 3 pins. I looked into it further today and thanks t...
